它可以：

* 在响应中返回状态码
* 在 OpenAPI 概图（及用户界面）中存档：

/// note | 注意

某些响应状态码表示响应没有响应体（参阅下一章）。

FastAPI 可以进行识别，并生成表明无响应体的 OpenAPI 文档。

## 关于 HTTP 状态码 { #about-http-status-codes }

/// note | 注意

如果已经了解 HTTP 状态码，请跳到下一章。

///

Имейте в виду, что можно добавлять проприетарные HTTP-заголовки [с префиксом `X-`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers).

Но если вы хотите, чтобы клиент в браузере мог видеть ваши пользовательские заголовки, необходимо добавить их в настройки CORS ([CORS (Cross-Origin Resource Sharing)](cors.md)), используя параметр `expose_headers`, описанный в [документации по CORS Starlette](https://www.starlette.dev/middleware/#corsmiddleware).

Der `TestClient` basiert auf [HTTPX](https://www.python-httpx.org) und glücklicherweise können wir es direkt verwenden, um die API zu testen.

The `TestClient` is based on [HTTPX](https://www.python-httpx.org), and luckily, we can use it directly to test the API.

## Example { #example }

      val expectedReason = reasons[i / 100]
      assertThat(response.status).isEqualTo("HTTP/1.1 $i $expectedReason")
      assertThat(headersToList(response)).containsExactly("Content-Length: 0")
    }

  @Test
  fun setStatusControlsWholeStatusLine() {
    val response = MockResponse().setStatus("HTTP/1.1 202 That'll do pig")
    assertThat(headersToList(response)).containsExactly("Content-Length: 0")
